Abstract: An imaging apparatus includes an imaging member having a surface, a development component that is not in physical contact with the imaging member, and a power source for generating an electric field between the imaging member surface and the development component. An ink is electrohydrodynamically transferred from the development component to the imaging member surface when the electric field is generated.

Abstract: Methods and devices provide an electrostatically chargeable surface within a printing apparatus and cause a movable lubricant applicator to contact the electrostatically chargeable surface. The movable lubricant applicator is movable to be in contact with the electrostatically chargeable surface, or out of contact with the electrostatically chargeable surface. Such methods control the movable lubricant applicator to be in intermittent contact with the electrostatically chargeable surface during printing operations of the printing apparatus.

Abstract: There is described an image forming apparatus including an imaging member having a charge retentive-surface for developing an electrostatic latent image thereon, a substrate and a photoconductive member disposed on the substrate. A bias charge roller for applying an electrostatic charge on the charge retentive surface to a predetermined electric potential is included in the image forming apparatus. The bias charge roller includes a first circumferential area in contact with the photoconductive member (CC[contact]), and a second circumferential area (CC[non-contact]) spaced a distance of from 1 μm to 1 mm from the photoconductive member. The image forming apparatus includes a power supply for supplying an oscillating voltage signal to the bias charge roller wherein the oscillating voltage signal has a frequency Am[fAC] and an amplitude Am[VAC]. The following relationship is met: (CC[contact]/CC[non-contact])≦(Am[fAC]/Am[VAC])≦(CC[non-contact]/CC[contact]) by the image forming apparatus.

Abstract: Methods for lubricating an imaging member include applying lubricant-containing capsules to the surface of the imaging member via a non-contact applicator. The capsules are applied upstream of a cleaning blade after image transfer to another substrate, such that the cleaning blade ruptures the capsules, thereby releasing the lubricant contained therein.
